D900: Methods of Teaching Secondary Mathematics

A study guide to the undergraduate Methods of Teaching Secondary Mathematics course at WGU, on differentiation, questioning, co-teaching and inclusive practice.

Updated October 2026 · 5 min read

Methods of Teaching Secondary Mathematics at Western Governors University (WGU) draws the line between knowing maths and teaching it. WGU says the course has no required prerequisites.

Its focus is effective teaching practice: differentiation, questioning, curriculum development, humanizing approaches, co-teaching, Multi-Tiered Systems of Support (MTSS), accommodations and inclusion. The difficulty is writing plans specific enough to teach, instead of general statements about good teaching.

What D900 Covers

These competencies are from WGU's graduate program guide for the same course; check your course page for the undergraduate wording.

Competency (WGU wording, summarized)What it means in practice
Analyze a recommended curriculum resource and its implementation in a secondary maths settingJudging how a resource would work in a real classroom
Apply methods by developing curriculum, using effective questioning and differentiating for diverse needsPlanning lessons that reach different learners
Create an instructional plan using relevant resources or technologyChoosing tools with a clear purpose
Reflect on secondary maths lessons and the specialized knowledge needed to teachLearning from what happened and why

Key Concepts Explained

Differentiation and MTSS

Differentiation adjusts content, process or product to student needs. MTSS organizes support in tiers: Tier 1 is high-quality instruction for everyone, Tier 2 adds targeted small-group support and Tier 3 provides intensive individual support.

Example: In a lesson on solving two-step equations, Tier 1 uses a balance-scale model and worked examples for the whole class. For Tier 2, a small group uses algebra tiles and sentence frames to explain each step. For Tier 3, a student who struggles with integer operations gets short, focused practice on that skill before returning to the equation. The plan says how you would decide who needs which support.

Questioning

Move from questions with one answer towards questions that expose reasoning, such as "How do you know?" and "What would change if...?". Plan a few key questions and a way to give every student thinking time.

Co-Teaching

Common models include one teach, one assist, parallel teaching and station teaching. Pick the model that fits the lesson goal and explain how the two teachers share planning and assessment.

Building a Differentiated Plan

Write your plan in this order so each decision follows from the one before.

StepDecisionEvidence to include
1Learning goalA measurable objective
2Learner needsReadiness, language, accommodations
3Tasks and questionsCore task plus supports and extensions
4Check for understandingWhat you will look for and what you will do next

Humanizing Mathematics Instruction

WGU's description lists humanizing approaches. In practice this means treating students as people with ideas, not as empty containers.

When writing a plan, give one concrete example of each practice you claim, such as a routine in which students compare two correct methods.

Curriculum Development in a Lesson Plan

Curriculum development in this course is practical: choosing and sequencing tasks, not writing a whole program. Show how a lesson sits inside a unit.

LevelQuestionYour answer should show
UnitWhat big idea does this lesson serve?The idea and its place in the sequence
LessonWhat should students be able to do?A measurable objective
TaskWhat will students actually do?A specific problem and expected strategies

Study Tips for D900

How We Help with D900

Send the prompt, rubric and the topic or grade band. A mathematics education writer prepares a custom plan, reviews your draft or helps you think through supports and questions.

GradeEssays is independent of WGU. Our work is a study and reference aid. Use it to learn the approach, then write and submit your own work under WGU's academic integrity policy. We do not complete classroom or clinical requirements for you. Orders are written from scratch, with free revisions within the scope of your original request and a full refund if late.

Frequently Asked Questions

Are there prerequisites for D900?

WGU says there are no required prerequisites.

How is D900 different from D906?

D900 is the undergraduate course. D906 is the graduate version, which leans more on analyzing a curriculum resource and reflection.

What is MTSS?

A Multi-Tiered System of Supports that provides instruction and help at increasing levels of intensity.

What is the difference between an accommodation and a modification?

An accommodation changes how a student accesses learning. A modification changes the learning expectation.

Does the course need real classroom work?

Check your task. If a classroom component is required, we cannot do it for you, but we can help you plan and reflect.

Can you review my lesson plan?

Yes. Send the task and plan and we check differentiation, questioning and rubric coverage.
